(Problem to be solved by the invention) However, in the parking facilities mentioned above.

It is desirable to secure a larger number of parking spaces by making effective use of space, and it is particularly advantageous to increase the number of parking spaces in small buildings to one per floor and two per second floor.

Therefore, two objects of the present invention are to use a tray retracting/extracting device for vertically feeding the tray in place of the conventional double-tray vertically feeding device, and to make the moving pin of the drive chain an overhang type so that the forklift can extend the vertical feeding. To provide a multi-layer planar circulation type parking facility capable of increasing the number of parking spaces by making it possible to pass when going up and down even if the facility is on a line.

(Means for Solving the Problems) Therefore, according to the present invention, a vertical rail and a horizontal rail are provided on the lifting frame of the forklift, and are connected to the vertical feed fixed rail and the horizontal feed fixed rail, respectively, so that the forklift is attached. A tray vertical feeding device is installed on both sides of each row of trays to vertically feed the trays using two endless chains driven and circulated in a horizontal plane within a range equal to the total length of the trays plus the distance between the tray rows. are connected by two hook-shaped connecting arms at or near half of the total length of the tray, and a movable pin that engages with the vertical feed guide groove of the tray is erected on these arms so as to overhang. This is what I did.

(Embodiment) The present invention will be explained in further detail using an embodiment shown in FIGS. 3 to 9, with the same parts as in FIGS. 1 and 2 denoted by the same reference numerals.

In FIGS. 3 and 4, a car entering through the entrance/exit 14 is placed in advance on a tray 1 on a lifting frame 7 waiting at the entrance by the operation of a forklift 4, and the lifting frame is lowered. As a result, the storage level of the parking unit U on the underground 2nd floor is reached, and the horizontal feeders 2□, 2
A pair of rotating arms 16, 16 whose tips are engaged with guide grooves 15 formed on the back side of the adjacent trays 1 are rotated to move the trays in opposite lateral directions.

In addition, the forklift 4 installed in the rear row on the left side of each parking device unit U is located at the lower pit 1 of the lift column 17.

When the lift frame is lowered from the two-dot chain line position to the solid line position, the counterweight 21, which had been at the lower position, becomes the solid line position, and when the lifting frame rises to the two-dot chain line position, the counterweight 21 is at the lower position. .

Next, for the vertical feeding of the I-ray 1, instead of the tray vertical feeding devices 2□, 2□ as shown in FIGS. 1 and 2,
A tray vertical feeding device 22 having almost the same structure as the tray retracting/extracting device 13 similar to the previous one. ．． 22 degrees, and both of these tray vertical feeding devices are installed on both sides of the front tray row to which the forklift 4 is not attached, and the structures of the two tray vertical feeding devices are exactly the same. .

Only one tray vertical feeding device 221 will be explained.

As shown in FIGS. 5 to 8, the tray vertical feeding device 22□ mainly includes a geared motor 23, a bevel gear pair 24 directly connected to the motor (FIG. 7), a main drive sprocket 25, and a driven sprocket 26. and upper and lower driving sprockets 2 which are coaxially attached to the driven sprocket.
7 and upper and lower driven sprockets 29 on which two endless chains 28 driven by the upper and lower driven sprockets 29 are connected, and in this case, as shown in FIGS. 6 and 7, the bevel gear pair and the main The driving sprocket is attached to a drive shaft 32 that is pivotally mounted inside the pedestal 30 via a pair of bearings 31, and the driven sprocket and the driving sprocket are attached to a drive shaft 32 that is pivotally mounted on the inside of the pedestal 30 via a pair of bearings 31.
These sprockets are driven by a chain 35 mounted between the main drive sprocket and the driven sprocket.

Further, as shown in FIG. 8, the upper and lower driven sprockets 29 are attached to a drive shaft 38 that is pivotally installed outside the pedestal 36 via a pair of bearings 37. Two endless chains 28 mounted on sprockets 29 and driven and circulated in a horizontal plane

At the tip of the tray 1, there is a traction roller 43 that fits into a groove-shaped latch 15' (Fig. 5) provided at the front left corner of the back surface of the tray 1.
, 44 is the installation. Furthermore, chain guides 45 are provided on both sides of the pedestals 30 and 36, and in order to prevent the two endless chains 28 from slacking and to provide smooth circulation drive, a plurality of chain guides 45 are provided on the chains at equal pitches. Guide rollers 46 and 47 are attached to the guide roller (not shown) and the two connecting arms 39 and 40, respectively.

(Function) In Figures 3 and 4, the left tray vertical feed device 22
□ is installed in the space 48 on the front side of the forklift 4 and on the bottom surface of the left end tray 1 of the front tray row in an area that is the total length of the tray plus the distance between the tray rows, and the right tray vertical feed device 22 □ is installed at the right end of the front tray row. Tray vertical feeding devices 22□, 22□ and tray horizontal feeding device W3□ are installed on the lower surface of the tray 1 in the same range as before, and the trays are moved vertically and horizontally in opposite directions simultaneously in synchronization. The operation of 3□ moves and circulates in a two-step system to carry out the loading and unloading of automobiles. The transverse wheels 5 run on the fixed rail 50 and the longitudinal wheels 6
is free).

When vertically feeding, move vertically on the vertical feeding fixed rail 51 @ 6
is traveling (the transverse wheels 5 are in a free state).

According to the present invention, the tray vertical feeding devices 2□, 21. is removed, and the vertical tray feeding device 22. ．． 22□
, respectively, so that an additional tray 1 can be placed in the dead space S1.

When the forklift 4 passes through the end of the adjacent tray row of the underground one-level parking unit U, in conventional parking equipment, the two-drive endless chain 28' is connected as shown in FIG. 9(b). Since the movable pin 42' attached to the arm 40' is unoverhanged, the tooth tip of the driven sprocket 29' is placed on the forklift so that the end surface of the transverse tray 1 placed on the forklift is flat. However, according to the parking equipment of the present invention, as shown in FIG. 9(a), the connecting arm of the endless chain 28 Since the moving pin 42 attached to the forklift 40 has an overhang, when the lifting frame 7 of the forklift 4 passes the end of the tray row, the moving pin escapes to the solid line position, and the forklift is rotated. When stopped at the level, the moving pin turns to the broken line position and stops, after which the tray 1 can be moved and circulated in the vertical and lateral directions.

Note that since the driven sprocket 29' is set back by the length Q to the position of the driven sprocket 29, there is a gap between the sprocket tooth tips and the tray 1 on the lifting frame 7 of the forklift 4 in a plane. Since the gap C is formed, the lift can pass through, and the core of the moving pins 42, 42' in this case remains unchanged.

(Effects of the Invention) As described above, according to the present invention, a vertical rail for vertical tray feeding and a horizontal rail for horizontal tray feeding are laid on the lifting frame of a forklift.

On both sides of the tray row where forklifts are not attached.

Because the tray vertical feeding device, which vertically feeds trays using an endless chain with overhanging moving pins, has been revised, the number of parking spaces will be reduced to one per layer and two per layer.
In addition, since a gap is formed between the tray on the lifting frame of the forklift and the tips of the teeth of the driven sprocket, the lifting frame can mutually contact each other when the end of the tray row passes. The lift can be raised and lowered without interference, and the tray can be moved and circulated in the vertical and lateral directions.
